A couple toggle bolts will hold that right where you need it to.
For the humid it depending on the lamp and ballast combation but with vapour tight luminaire as you have there that should not affect much as open luminaires are.That's exactly what Im going to do. The vaportight was partially bought to reduce dust and bugs.
Is it true or not that the humidity is what kills a ballast so that it stops working and lighting a GOOD bulb when its humid out?
Did you read the model number of that luminarie ? if it was the same with other then someone might got that swapped or have differnt verison due there are few luminaires that are wired for 277 volts so that may get your attetion on that part.Got all 6 of the 8 dual element T5HO fixtures up. They are bright. Like...awesome bright. They replaced aging T12. Seriously, they are sweet. Not sure about the diffuser, its somewhat of an orange peel type, maybe a different one would be better, but at 9' hight, I think its best this way. I can finally see to work on my car and woodworking stuff. Awesome.:thumbsup:
Noticed ONE fixture seemed to have a different ballast in it for some reason, Not sure if that matters. I have extra fixtures since one has a busted diffuser. Any reason to change out that ballast?
Naw don't worry about them right now the T5-HO ballast will become more common as the time go by but just becarefull when you get replacement lamp that only part it will bite ya. It the same way with T-8's or T-12'sIll just take that fixture back. These came from a box store, and I buy extras because inevitably, ONE is always broken somehow or another. Ill just take it back, no worries.
Cool that will be good.
The fixture with the different ballast is the same as teh rest, but I didn't know if it would make it easier to buy new ballasts in 8 years if they were all the same, or if that will be any problem at all?
